Because Extron System 8/10 Switchers are universal and are capable of controlling and communicating with many brands of large-screen projectors, the desired communication adapter must be selected for the brand of projector that the switcher will be connected to. The communication adapter adapts the switcher's projector control port to the control port on the projector. Because the System 8/10 Plus Switchers are compatible with every one of the projectors listed below, if the projector in an installation or rental application changes, the only things that need to be changed are the communication adapter and a few of the front panel DIP switches.
